London regulator announces Uber ban

London's taxi regulator is revoking Uber's license to operate in the city, the agency announced on its Twitter feed on Friday morning. "Uber's approach and conduct demonstrate a lack of corporate responsibility," Transport for London wrote.

The agency cited Uber's "approach to reporting serious criminal offenses" as one problem with the company's conduct. It also pointed to Greyball, a controversial software program Uber allegedly used to mislead regulators about the locations of its cars, making it more difficult for regulators to ticket Uber vehicles.

Uber's license expires on September 30. However, it has 21 days to appeal the agency's ruling, and it can continue operating in the city during the appeal process.
